To (1.7? 'whom it may/concern Be it known that I, EUGNE SOLOMON MANXY, asubject of the King of Great Britain, and a. resident of the city ofMontreal, in the Province of Quebec, in the Dominion of Canada, haveinvented certain new and useful Improvements in Hot-flater Heaters; andI do hereby declare that the following `is a full, clear, andexactdescription of the-saine.

T he invention relates to improvements in hot water heaters, asdescribed in the present specification and illustrated in theaccompanying drawings that forni part ofthe saine. A

The invention consists essentially in the novel construction andarrangement Ofparts, whereby the water is thoroughly heated andmaintained at a predetermined tenipeinture.

The obyects of the invention are to devise an etlicient water heatingdevice, which shall utilize the steam from a steam plant in heating thewater for distribution throughout a building, and generally to providein a, simvple and inexpensive manner an automatic means of controllingthe supply of the heat- In the drawings, 'Figure-l is a longitudinalsectional View of the lower heater casing and a vert-ical sectional Viewof the inlet yalve. 'F ig. '2 is alongit-udinal sectional Like numeralsof reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is a casing,

preferably cylindrical, and closed at theends-by the. heads 2 and 3 andhaving a water inlet 4 through the under side thereof and the wateroutlets 5 and 6 through the upper side thereof, said head Q forming a]casing containing the steam chest 7 and the condensation chamber S,separated by the division wall 9.

10 isa steaminlet opening tov the` steam -chest 7.

11 isaii Outlet opening at the lower end of the condensation chamber S.

l j -12 is a lug extending downwardly from the head 2 and preferablypart therewith.

a tube opening toward the lower end of the ,-Ll,iead .8. u

l-L is a pipe rigidly secured to the water inlet 4. and connected with asuitable water supply and through which the water is fed p into thecasing 1. Y 1 is a pipe extendiiig"tli.rough the division wall 9 andinto the Outer 'wallI of the head leading to the air valve 16 andforming a passage for the air from th'e conf.

densation chamber S to said air valve.

H a l y 1i are pipes having lthe closed ends 18 and rigidly secured attheiropen ends in the" communicating with the. steam cllte'st 7 andterminating at their other" ends adjacent to the closed .ends 18 of thepipe 17, thus the st eani from the chest 7 -iows through said pipes 19and'o'ut through the Aopen ends ih'io the pipes 17, returning tothecondensation chamber 8.

`20 is a `casing hav-ing the inlets'Ql and Q2 registering with theOutlets 5 andi and rigidly secured, said casing containing similar pipesto Ithe pipes 17 and 19, though fewer in number,l said casing 2O havinga steam chest in one of its heads cOnne'ctedlI-f to the steam chest 7 by'the pipe :'2-1. 25 isj the condensation chamber in the saine head"andin.precisely' the same arrangement as 'in the condensation chamber S`this casing being for the purpose of more easily increasing thetemperature of the water pass- .ing through said casing.

is an opening through the upper side of the casing 20 vto which thedistributing pipes are connected. f

27 is the expansion member formed of a tube, screw threaded at its Outerend into the ring 2S, said ring being rigidly secured to the head 3 overthe tube opening 13, the said tube-passing freely through said Openingand terminating in the closed end QS) with the threaded Orifice y30therethrough, said closed end being in the vicinity of the inner wall ofthe head 2. .The'tube 27 is vsupported entirely from the ring 2S and itwill also be noticed that all the pipes are supported from one end, thusallowing for expansion and contraction' without fear of damage. to thepipes.

31 is 'a bar haring the end thereof turned and screwvthreaded into theOrifice 30,v the tongue.v

outer end oi said bar entendin beyond the outer end oi the tube 2i inthe :term of a 33 is a :forked lug having the pivot pin 34 across theprongs thereof and extending outwardly from the upper side oi the ring28.

is a linl: having at the upper end thereof and from the outer side theslot 36 and engaging said pivot 34 in said slot and on the inner sideengaged by the outer end 82 oi the ber 3l.,

3'? is a connecting rod at one end pivotally :secured at the lower endof the linlr 35.

38 is a bracket rigidly secured to the unie side oi the lug l2 andhaving a vertical 89 therethrough and an extending bar 4u at the lowerend thereof, said bar 40 having the upwardly odset end 4l and the it-shaped hearing 42 in the inner wall of said odset 4le 48V is a cranklever having the short upwardly extending section 44 pivotally securedto the end of the connecting rod 37 and the horizontal long section 45extending through the vertical slot 88 said crank lever 4l at the angleend terminating in the spear point 46, said spear point engaging in theif-shaped hearing 42, thus providing a i'ulcruifn for the crank. leverby means of which the long section 45 may he raised through theoperation of the link 35 and its connection withthe bar 31.

47 is 'a weight having a slot 48 therethrough iromend to end, said slothaving the inclined bed 49.

' '50 are lugs extending from the upper side oi the weight 47 and havingthe vertical slots 5l therein from the upper side thereof. f

5.2 is a set screw threaded into the upper side of the weight 47 towardthe outer end thereof and extending through to the slot 48.

58 is a pivot through the reduced inner end of the weight 47 andsecuring the weight to the long section 45 of the crank lever, saidcrank section 45 extending through the slot 48 and engaged by the setscrew 52a 54 is a valve casing having a double seat 55 and and the inlet57 connected to a .euitable'steam supply on the one side of said 'seatsand the outlet 58 on the other side of said seats leading into the steaminlet open ing 10, said valve casing at the extremity of the outletpassage 58 having a flange 59 rigidly secured around said steam inletopening .l0 by the cap screws 60. 6l is avalve engaging the seats 55 and56 and having the stein 62 projecting upwardlvinto the rel duced end ofsaid 'valve casing.

. ,64 is a. spiral spring encircling the valve stem 62 and holding thevalve 61 down on to its seats. The reduced upper end 63 of the, valvecasing'is closed-inby the removable 65. l

is a rod extending upwardly in the red leed ylower end'? of the valvecasing and niiaeee engaging the 'bottom of the valve 6l for the purposeof opening said valve, said rod 66 extending downwardly below the saidreduced end 67 and suitably packed.

68 is a link having laterally extending pins v69 at the lower endthereof engaging at the bottom of the vertical slots 5l and at the upperend thereof secured to the lower end of the rod 66 by the pin 70.

in the operation of this invention, the water is ted through the inlet 4and spreads over the interior of the casing l around the pipes17,branching at each side and leaving sai-.d casing through the outletsand 6 into the second casing 20 and through said second casing 20 aroundthe pipes ni'said casing to the outlet 26 and so on into thedistributing pipes through the building to be heated and then back tothe casing l., The ywater-is heated by means of the steam entering thesteam pipes in each casing from the steam chest at the end thereof, saidsteam flowing through said steam lpipes into the encircling pipes andback to the condensation chambers, thus heating .the water passingaround said pipes. So long as the water remains cool, the valve 61 isopen and allows the ingress of steam as the tube 27 is then in itscontracted position, which znoves the bar 3l outwardly and pushes thelink 35, said link swinging on its pivot and drawing at its lower endthe connecting rod 37 which pulls on the crank lever 43 and pulling onsaid crank lever 43 raises the long section 45 vof the lever and throughthe link 68 and rod 66 raising the valve 6l to its open position againstthe pressure of the spring 64. ils soon as the water becomes very hotthe metal of the tube 27 expands and draws with it in its expansion thebar 31. This releases the link 35 and the weight 47 then brings the longsection 45 of the crank lever to its original horizontal position, thuspermitting the spring 64 to close the valve 6l'.

It willbe seen that the steam passes fromV the chest 7 to the chest 23through the pipe 24, though there is a valve 71 operated by a suitablehand wheel 72 for cutting o the' steam connection between the two casngsin l mild weather.
